9.13. Message Disposition Notifications (MDN) - Extended Feature
The confirmation of delivery and processing are extensions to "Simple Mode of Facsimile Using Internet
Mail" [RFC2305]. These are designed to be interoperable with the existing base of mail transfer agents
(MTAs) and mail user agents (MUAs), and take advantage of existing standards for advanced functionality
such as positive delivery confirmation and disposition notification. The following two features are combined.
(1) Delivery confirmation (required)
(2) Additional document features (optional)
In Internet Mail, the operations of Delivery (to the mailbox) and Disposition (to paper or a screen) may be
separated in time (due to store and forwarding of messages) and location (due to separation of delivery
agent (MTA) and user agent (MUA)). The confirmations of these two operations are supplied by two
different standards-track mechanisms: Delivery Status Notifications (DSN) [RFC1891, RFC1894] and
Message Disposition Notifications (MDN) [RFC2298], respectively.
Your Panasonic device supports MDN.
Delivery Status Notification (DSN)
A DSN can be used to notify the sender of a message of any of several conditions: failed delivery, delayed
delivery, successful delivery, or the gatewaying of a message into an environment that may not support
DSNs. Panasonic Internet FAX does not request DSN while sending.
Message Disposition Notifications (MDN)
A MDN can be used to notify the sender of a message of any of several conditions that may occur after
successful delivery, such as display of the message contents, printing of the message, deletion (without
display) of the message, or the recipient's refusal to provide MDNs.
The MDNs are expected to serve several purposes such as allow mail user agents (Outlook Express) to
keep track of the disposition of messages sent, by associating returned MDNs with earlier message
transmissions.
